TABrinn Posted June 20, 2008 Share Posted June 20, 2008 I Just got my car back from paint and have started to really dig into it to see what all needs done. A$$ backwards, I know! I just popped off the valve cover to see how things looked and there were metal "hairs" everywhere!!! I don't know if one of the PO's rebuilt the engine of not, or how many miles are on it since. I'm thinking I should tear it all down but really don't want to pull the engine if at all possible. Can you rebuild a 240Z engine with it still in the car, assuming the block doesn't require any machine work? Quote Link to comment Share on other sites More sharing options...
cockerstar Posted June 20, 2008 Share Posted June 20, 2008 A full rebuild? No. If there are metal shavings in there, you've got some serious problems. Pictures of the damage? Quote Link to comment Share on other sites More sharing options...
TABrinn Posted July 6, 2008 Author Share Posted July 6, 2008 I fished around with a magnet and the shavings are magnetic. The best I can figure is that the cam towers are misaligned, binding the cam up, or something is screwy with the rockers/ lashpads. For peace of mind though I want to rebuild the whole thing. Does anyone know of a good machine shop in south Texas? There aren't any here in Corpus Christi that have any experience with these engines. San Antonio maybe?

blue72 Posted July 7, 2008 Share Posted July 7, 2008 Shemp? I think if it were your cam towers interfering with the rotation of the cam that you would have aluminum shavings, not magnetic steel ones. The softer metal of the cam towers would sooner disentigrate than the ultra hardened steel of the camshaft. I rebuilt my L-28 on the garage floor very carefully. More than likely the engine is junk if there are floaty metal bits all over. Did it run before this? Did you drive it? If not I'd break out the tools and begin the teardown to determine the cause of the problem. Quote Link to comment Share on other sites More sharing options...
Tony D Posted July 7, 2008 Share Posted July 7, 2008 When cam towers are misaligned, they tend to seize the cam bearings, and then the camshaft snaps... Now you guys see the importance of epoxy-gluing a cow magnet at the front and back of the head, as well as in the oil sump, and hose-clamping several around the periphery of the oil filter. Especially for original break-in! Quote Link to comment Share on other sites More sharing options...
TABrinn Posted July 8, 2008 Author Share Posted July 8, 2008 Yes they are curly. Like a bunch of magnetic pubes! If the cam was only slightly misaligned wouldn't it eat up the bearings first? The bearings are magnetic right? Cow magnet??? The engine was mostly together when I bought the car but needed obvious work to even start. Missing fuel lines, battery, fuel pump uninstalled, throttle linkage for the trip webers needed hooked up, etc. Needless to say I knew then, as I do now, that a full rebuild was a definate possibility. Does anyone know of a reputable machine shop in the south Texas area??? Quote Link to comment Share on other sites More sharing options...

Careless Posted July 8, 2008 Share Posted July 8, 2008 Northern Tool sent me a catalog that had a magnet that actually screws onto the base and is a magnetic pre-filter to the oil filter itself. looks good! Quote Link to comment Share on other sites More sharing options...

Daeron Posted July 13, 2008 Share Posted July 13, 2008 had to google "cow magnet." brutal. My question is.. would that part be considered an "engine internal?" Quote Link to comment Share on other sites More sharing options...
